The moral of the story is this: If you are wavering about getting protection for your cylinder heads on your shiny new GSW, don't hesitate. Even if you never plan to leave the pavement, one little tip over can ruin your night.

For a 'crash' like that the TT cilinderheadcovers (or something simular) work perfectly. They deform a little and absorb the energy. but after a decent drop you can replace them.
